the other platonic solids

Here are the changes in the steps needed to make the other platonic solids:

cube

  • gather materials and tools
    • 27 cards, 24 for the cardahedron
  • cut template card
    • use 45° and 45°
    • guide
  • join cards
    • 4 cards join at each corner, and 4 join at the center of each face

octahedron

  • gather materials and tools
    • 27 cards, 24 for the cardahedron
  • join cards
    • 4 cards join at each corner with the 30° slot, and 3 join at the center of each face with the 60° slot

dodecahedron

  • gather materials and tools
    • 63 cards, 60 for the cardahedron
  • cut template card
    • use 54° and 36°
    • guide
  • join cards
    • 3 cards join at each corner with the 54° slot, and 5 join at the center of each face with the 36° slot

icosahedron

  • gather materials and tools
    • 63 cards, 60 for the cardahedron
  • join cards
    • 5 cards join at each corner with the 30° slot, and 3 join at the center of each face with the 60° slot

It is also possible to make stellated solids with this method... and changing to an edge-oriented technique (where a folded card forms each edge) allows lots of irregular solids too...
